Abstract: The present disclosure provides an exciter and an electronic product. The exciter comprises: a magnetic circuit assembly comprising a first housing and a magnet, and the magnet is connected to the first housing; a coil assembly comprising a second housing and a coil, and the coil is disposed in a magnetic field formed by the magnet, wherein the coil assembly is configured to be capable of generating a vibration relative to the magnetic circuit assembly, the coil is formed by winding a wire having a polygonal cross section. According to the present disclosure, the coil wire has a polygonal cross section, so that an interval between the wires can be reduced in the wound coil, the number of turns of the coil is increased in the same space, the effective length of the coil is increased, and the driving force generated from the coil is increased.
